+ARECA FIRMWARE SPEC
+===================
+
+Usage of IOP331 adapter
+=======================
+
+(All In/Out is in IOP331's view)
+
+1. Message 0
+------------
+
+- InitThread message and return code
+
+2. Doorbell is used for RS-232 emulation
+----------------------------------------
+
+inDoorBell
+    bit0
+	data in ready
+	zDRIVER DATA WRITE OK)
+    bit1
+	data out has been read
+	(DRIVER DATA READ OK)
+
+outDooeBell:
+    bit0
+	data out ready
+	(IOP331 DATA WRITE OK)
+    bit1
+	data in has been read
+	(IOP331 DATA READ OK)
+
+3. Index Memory Usage
+---------------------
+
+============   ==========================================
+offset 0xf00   for RS232 out (request buffer)
+offset 0xe00   for RS232 in  (scratch buffer)
+offset 0xa00   for inbound message code message_rwbuffer
+	       (driver send to IOP331)
+offset 0xa00   for outbound message code message_rwbuffer
+	       (IOP331 send to driver)
+============   ==========================================
+
+4. RS-232 emulation
+-------------------
+
+Currently 128 byte buffer is used:
+
+============   =====================
+1st uint32_t   Data length (1--124)
+Byte 4--127    Max 124 bytes of data
+============   =====================
+
+5. PostQ
+--------
+
+All SCSI Command must be sent through postQ:
+
+    (inbound queue port)
+	Request frame must be 32 bytes aligned:
+
+	    #bit27--bit31
+		flag for post ccb
+	    #bit0--bit26
+		real address (bit27--bit31) of post arcmsr_cdb
+
+		=====   ===================
+		bit31   ==  ===============
+			0   256 bytes frame
+			1   512 bytes frame
+			==  ===============
+		bit30   ==  ==============
+			0   normal request
+			1   BIOS request
+			==  ==============
+		bit29   reserved
+		bit28   reserved
+		bit27   reserved
+		=====   ===================
+
+    (outbount queue port)
+	Request reply:
+
+	    #bit27--bit31
+		    flag for reply
+	    #bit0--bit26
+		    real address (bit27--bit31) of reply arcmsr_cdb
+
+		    =====   =======================================================
+		    bit31   must be 0 (for this type of reply)
+		    bit30   reserved for BIOS handshake
+		    bit29   reserved
+		    bit28   ==  ===================================================
+			    0   no error, ignore AdapStatus/DevStatus/SenseData
+			    1   Error, error code in AdapStatus/DevStatus/SenseData
+			    ==  ===================================================
+		    bit27   reserved
+		    =====   =======================================================
+
+6. BIOS request
+---------------
+
+All BIOS request is the same with request from PostQ
+
+Except:
+
+Request frame is sent from configuration space:
+
+	============   ==========================
+	offset: 0x78   Request Frame (bit30 == 1)
+	offset: 0x18   writeonly to generate
+		       IRQ to IOP331
+	============   ==========================
+
+Completion of request::
+
+	(bit30 == 0, bit28==err flag)
+
+7. Definition of SGL entry (structure)

+RS-232 Interface for Areca Raid Controller
+==========================================
+
+      The low level command interface is exclusive with VT100 terminal
+
+1. Sequence of command execution
+--------------------------------
+
+	(A) Header
+		3 bytes sequence (0x5E, 0x01, 0x61)
+
+	(B) Command block
+		variable length of data including length,
+		command code, data and checksum byte
+
+	(C) Return data
+		variable length of data
+
+2. Command block
+----------------
+
+	(A) 1st byte
+		command block length (low byte)
+
+	(B) 2nd byte
+		command block length (high byte)
+
+		.. Note:: command block length shouldn't > 2040 bytes,
+			  length excludes these two bytes
+
+	(C) 3rd byte
+		command code
+
+	(D) 4th and following bytes
+		variable length data bytes
+
+	    depends on command code
+
+	(E) last byte
+	    checksum byte (sum of 1st byte until last data byte)
+
+3. Command code and associated data
+-----------------------------------
+
+The following are command code defined in raid controller Command
+code 0x10--0x1? are used for system level management,
+no password checking is needed and should be implemented in separate
+well controlled utility and not for end user access.
+Command code 0x20--0x?? always check the password,
+password must be entered to enable these command::
